Abstract

It is pointed out that if the QGP SU(2) chiral phase transition in the LHC PbPb collision process is taken place and the phase transition is in the second order， then pion strings will be formed， and decay. These phenomena lead to the pion enhancement in the low momentum region(p150—400 MeV) and the number of pions produced from pion string decay can be estimated about Nt≈270， 150， 60 for different freeze temperature Tf=130， 120， 110 MeV respectively.
